Audit source (source_type=audit), off until enabled in Settings > Sources:
- follows /var/log/audit/audit.log (path configurable, AUDIT_LOG), with
rotation (end of audit.log.1 read first) and an offset checkpoint in
/data/audit-state.json; last AUDIT_BACKFILL (1h) read on first enable
- groups the records of an event by msg=audit(time:serial), closed on EOE,
after 2 s without a record, or once the log has moved 2 s past it
- fields audit_type, audit_serial, auid, user (enriched name, host
/etc/passwd or uid), exe, res, key, audit_raw; app = audit_type, host =
node= / AUDIT_HOST / /host/etc/hostname; summary "who: what [key] →
result"; warning when res=failed / success=no, info otherwise
- hexadecimal values (proctitle, cmd, exec arguments…) decoded
Internal logs (source_type=logstream, host=logstream, app=component):
- logEvent() for VictoriaLogs unreachable / back, lost batches, spooled
batches refused, syslog listener errors, Docker API and container
streams lost, failing sources, start and stop
- on by default from warning; switch and minimum level in Settings >
Sources (/data/selflog.json)
- bounded queue, never waits for the Store, same event at most once per
30 s with a count of the repeats: a failing Store cannot loop
UI: violet (audit) and turquoise (LogStream) left edge and tint, AUDIT /
LS badge before the app, raw audit record under the summary (folded in
compact density until the row is opened), Audit and LogStream in the
source filter, FR/EN translations. docker-compose: optional
/var/log/audit, /etc/passwd and /etc/hostname mounts. README (EN/FR):
host prerequisites (log_group, ACL for UID 10001).

- SyslogServer opens and closes the UDP/TCP listeners at runtime from the
configuration saved in /data/syslog.json; a busy port no longer stops
Logstream, the error is shown in Settings instead.
- Sources tab: syslog section with an on/off switch, UDP and TCP labels,
the live listening state and the published port (SYSLOG_PORT, passed as
SYSLOG_PUBLIC_PORT for display; the mapping stays in docker-compose).
